Routing visualization user interface

ABSTRACT

A configuration of a service of a cloud computing system is rendered in a user interface of an electronic display, according to a discovery chain generated by a networking tool using a service discovery function to establish the configuration. The configuration includes one or more of a router, a splitter, and/or a resolver, each having one or more configuration files that are represented as a graphical element within a graphical representation of the one or more of the router, the splitter, and/or the resolver. The configuration further includes data traffic routes between pairs of the configuration files, each being represented in the UI as a line between each pair of configuration files, where each line is rendered in the UI so as to avoid crossing over any graphical element that represents a configuration file.

The current application is a continuation of U.S. Non-Provisional patent application Ser. No. 16/941,390, filed on Jul. 28, 2020, entitled “ROUTING VISUALIZATION USER INTERFACE”, which is incorporated by reference herein in its entirety

TECHNICAL FIELD

The subject matter described herein relates to routing configurations of a cloud-based computing infrastructure, and more particularly to a routing visualization user interface to visualize routing configurations for efficient service discovery and configuration management.

BACKGROUND

In cloud computing, service discovery is the detection of services (applications, microservices, etc.) and supporting resources (devices, networking hardware, etc.) in a cloud computing network, and their configurations (data traffic inputs and outputs, policies, event handlers, etc.). Such services are typically configured in one or more configuration files. Service discovery can reduce configuration efforts by users, which in turn can reduce possible errors or failures of those services and the resources they use. In some cases, such as in complex cloud networks with a large number of services, service discovery can take up valuable time and other resources. The service discovery process in a cloud computing infrastructure, particularly one using multiple cloud providers, is therefore a key in systems with a large number of services that can be discovered and connected with centralized policies for seamless interoperability and execution.

Some cloud computing providers use a networking tool that provides a service-mesh control plane, service discovery, configuration, and segmentation, for connecting and securing services across any runtime platform and public or private cloud. Such a networking tool enables an enterprise to secure and observe communication between services without modifying their code. In some instances, a networking tool configures “sidecar” proxies, which are local to an associated service for communications security, and which control network traffic between service instances to establish mutual transport layer security (TLS) between services and either allow or deny communication between them based on their registered names.

Networking infrastructure in the Open System Interconnection (OSI) model is defined by seven distinct layers. Layers L4-L7 predominantly define network services. For example, L4, the “transport layer,” allows direction of traffic based on data from network and transport layer protocols, such as IP address and TCP port. L7, the “application layer” nearest to an end user, provides information to a router for content switching for load balancing, among other functionality. Information from these layers allows for routing decisions based on attributes like HTTP header, uniform resource identifier, SSL session ID and HTML, form data. Service discovery tools can use the information from these layers to discover networking services as well as traffic between services.

In some cases, users can use a command line interface (CLI) or an application programming interface (API) to create service configurations using an infrastructure-as-code (IaC) service, such as Terraform® by HashiCorp. Nearly infinite configurations can be created for each service, and the configuration options can be extensive for each configuration type. Thus, users can quickly become confused about how exactly they have configured their traffic routing, and most particularly L7 traffic routing.

What is needed is a system and method by which a user can easily and more efficiently view the results of a service discovery process, to give users confidence that their configurations are routing traffic in the way they intended. Such a visual representation is also needed to present a way to troubleshoot traffic routing issues without having to scan numerous or complex configuration files.

SUMMARY

This document describes systems and methods for providing a visual representation in a web-based networking tool UI of a service discovery process of cloud computing services. The service discovery process can be modeled and represented as a “discovery chain” that passes through a number of distinct stages, or configuration types, as more fully explained below. Being able to visualize the discovery chain and its routing provides users confidence that configurations are routing traffic as intended. The systems and methods can be used to troubleshoot traffic routing issues, without having to scan numerous or complex configuration files.

In one aspect, configuration of one or more services of a cloud computing system is rendered visually, modeled as a discovery chain generated by a networking tool using a service discovery function. The discovery chain includes a set of configuration types that include one or more of a router, a splitter, and/or a resolver, each having one or more configuration files that are represented as a graphical element within a graphical representation of the one or more of the router, the splitter, and/or the resolver. The configuration further includes data traffic routes between pairs of stages that represent configuration files, each of the data traffic routes being represented in the UI as a line between each pair of configuration files. Each line is rendered in the UI so as to avoid crossing over any graphical element that represents a configuration file. Accordingly, a visual representation of each service's discovery chain is provided in a UI to give users confidence that their configurations are routing traffic in the way they intended. Such a visual representation also presents an easier way to troubleshoot traffic routing issues, without having to scan numerous or complex configuration files or other text-based documents.

DETAILED DESCRIPTION

This document describes systems and methods for providing a visual representation of a service discovery chain of cloud computing services. The visual representation can be provided in a web-based networking tool UI. Visualization of the discovery chain and associated routing provides users confidence that configurations are routing traffic among cloud-based services as intended. The systems and methods can be used to troubleshoot traffic routing issues, without having to scan numerous or complex configuration files. Consistent with implementations described herein, “routing” in this context is the sending of data traffic between two services or endpoints of a cloud computing infrastructure. The visualization is designed to convey the configuration of how traffic should be routed between the services and/or endpoints, for example, routing can be configured to send 50% of data traffic to version A and 50% to version B of a service.

As described herein, results of a service discovery process can be modeled as a “discovery chain” which passes through three distinct stages, each representing a configuration type: routing, splitting, and resolution. Therefore, in some implementations of a service discovery model of a networking tool for use for network configuration, there are can be three configuration types or entries: Routers, Splitters, and Resolvers. Each of these has a distinct functional role. Routers are used to determine where to route to in the cloud-based computing infrastructure, based on information such as a URL path. For example, “/login” requests may go to a login service, and “/billing” requests may go to a billing service. Splitters are used to split the traffic. For instance, an enterprise may want 90% of traffic to go to a present version of a computing resource or service, and 10% to a new version of the computing resource or service, in order to test a possible migration to the new version. Resolvers are used to “map” back to the service, e.g. when a service “billing-V2” is defined, a resolver determines that a service with name “billing” and a metadata property called “version” with a value of “2” is being sought for the application traffic. Each of these stages is controlled by a set of configuration types or entries.

Traffic between any two services can be routed through any number of intermediate proxies. These software modules are responsible for forwarding traffic, but also may provide additional logic or transformation. As an example, a proxy may be used to enforce access controls. A proxy upstream is the next “hop” in the connection. For example, system A connects to proxy B, which connects to system C. In this example, system C is the “upstream” of system B. Likewise, proxy B is the “downstream” of system C.

Proxies can be deployed with applications and are responsible for handling incoming and outgoing service connections of an associated application, and are controlled centrally within the cloud computing infrastructure. This allows the services to “push” changes to the proxies that affect how they will handle incoming and outgoing traffic. By configuring different phases of the discovery chain, a user can control how proxy upstreams are ultimately resolved to specific instances of a service for load balancing. For instance, when a proxy upstream is defined, that proxy upstream becomes the service that is ultimately resolved and connected to. A downstream service connects to an upstream service. Thus, when the downstream service initiates the connection, the discovery chain can be employed to determine which upstream service to connect to. The configuration types used in the discovery chain can be designed and rendered to be simple to read and modify for narro tailored changes, but at discovery-time the various configuration entries interact n more complex ways.

Users can set up each service to have anywhere from zero to all three configurations, as shown in FIG. 1A. However, no matter which configuration types the services are, traffic by the service will be routed in the same manner and order for each configuration: first the router (if present), then the splitter(s) (if present), then the resolver(s) (if present), as shown in FIG. 1B. In some cases these configuration types direct traffic through the configurations of another service, as shown in FIG. 1C. In most instances, traffic can only move forward or laterally in the discovery chain, not backwards, as illustrated in FIG. 1D.

Collecting information from an associated API and presenting it to a user in a useful or human-readable format is a common task in a user interface (UI) of an IaC service. Conventionally, hypertext markup language (HTML) is used to display API information due to its text rendering capabilities, accessibility and layout/stacking and reflow capabilities. But, HTML has considerable limitations, and is adequate only for displaying information in a UI using text and more or less rectangle-shaped “containers.”

This biggest issue with visualization of traffic routing in a UI is being overly complicated in terms of graphical representations: e.g., lines crossing lines, lines crossing boxes, difficulty in trying to make out which lines goes where or understanding at a glance by a user how much traffic is routing to which resolver, or difficulty hovering over the lines in order to understand the proportion of traffic going to a resolver subset. While users may start out with fairly straightforward configurations being rendered in a UI, more complicated visualizations are likely, and must be addressed. While there can be no guarantee that lines do not cross other lines, for maximum usability and in accordance with implementations described herein, lines crossing boxes, i.e. edges crossing nodes, are avoided to the extent possible.

FIG. 2A illustrates a visual representation, or visualization 200, of a service's discovery chain of traffic routing. One or more configuration entries of each of routers 202, splitters 204 and resolvers 206 can include one or more configuration files 208, or “nodes,” (e.g., the configuration files “/dashboard,” “/,” “/admin,” “/consul,” and “/db” in configuration type router 202) which are depicted as boxes within each of the routers 202, splitters 204, and/or resolvers 206 in FIG. 2A. The configuration files 208 can be rendered and depicted as any discernable shape within each representation of a configuration type 202, 204, and/or 206. In preferred implementations, routings 205 from configuration files 208 to other configuration files 208 between the routers 202, splitters 204 and resolvers 206 are depicted as curved lines with arrows, unless two configuration files 208 are rendered along the same horizontal line in the UI without having to cross an intervening configuration file 208, in which case the routings are depicted as straight horizontal lines as shown in FIG. 2A. Shapes other than arrowed lines can also be used.

The traffic routing visualization 200 can be read-only, showing the result of a service's L7 routing configuration files 208 without an ability for the traffic routing to be reconfigured or modified through the UI. In some implementations, a standardized Document Object Model (DOM) based approach can be used in order to render and display the lines and arrows on a layer underneath HTML-rendered information. This can allow using an existing tooling or framework to keep page re-rendering to a minimum when data representing the view of the discovery chain of traffic routing changes.

In such implementations, a language and format such as Scalable Vector Graphics (SVG) for the DOM can be used. SVG is an Extensible Markup Language (XML)-based vector image format using a declarative text-based format that fits in well with templating and DOM diffing capabilities, and has similar benefits to HTML. Those having skill in the art would recognize that other tools can be used. Preferably, the rendering technology is used to draw an overlay on top of the HTML rendered information containing the curved lines/arrows.

In order to calculate the path or “edge” from one node in the chain to another for the visualization, first the most straightforward calculation is used to draw a curved line from one node to another. In this first calculation, lines would be unavoidably rendered to cross each other. Further, lines will cross boxes, so initially the lines must be rendered in the UI at a lower layer to the boxes, and the boxes will be semi-transparent on top of the lines. In some cases, these issues can be mitigated somewhat by using user inputs 210 via a mouse or cursor to enable clicks/hovers on a particular graphical element to highlight a traffic flow of interest, thus making the visualization easier to follow, as shown in FIG. 2B. In other implementations, the lines representing the routings 205 can be drawn in such a way that they avoid crossing boxes.

In some implementations, for example, the UI can employ a graph traversal and path search algorithm such as A* to calculate the shortest/best path between the routes to the resolvers, while avoiding any obstacles (e.g. central column splitters) when required. This can then be rendered to SVG using a similar approach as outlined above. Those of skill in the art would recognize that any of a number of graph traversal and path generation algorithms can be used, particularly when employed to avoid crossing lines representing the paths.

Interactivity, in the form of one or more interactive functions, can be provided to the visualization 200 so that a user of the UI can interact with the visualization 200 in various ways. For example, using a graphical cursor and clicking on a box representing a configuration file 208 will isolate any related boxes and arrows that share the same pathway of routings 205. As shown in FIG. 2B, hovering the graphical cursor over a line can a split percentage or other data about the pathway of routings 205.

FIGS. 2A and 2B, described above, show the detail page for a service named “web.” Thus, the “web” routers, splitters and resolvers are rendered in the visualization 200. Routes can be rendered in the order they are set, as well as any failover configurations in the resolvers, which can be rendered as a separate configuration file. In preferred implementations, users are able to edit their L7 Routing configuration files directly from the UI, via direct interactive input to the UI.

In accordance with some implementations, blocking endpoints are a set of APIs which are able to delay responding (e.g. blocking) until there is a change detected. This allows a system to push real-time updates when configurations change. Upon a definition of new blocking endpoints, the visualization 200 can be ensured to represent the latest changes of the configuration, without needing the user to refresh the page of the UI. Ideally, as updates are made to the configuration files 208, those changes would appear independently, without the visualization 200 having to be re-written entirely from scratch because of a change.

Ultimately, the “route” traffic takes between two endpoints is governed by a central configuration that defines a set of rules for the routing, and which can be simple for most cases. Even in the rare case of a complex service that has many rules, those rules are likely to also be simple. For example, when the user isolates a splitter/resolver, such as by clicking on a selected configuration file 208 with a cursor, a rule can be established that some select routings are prominently displayed, while other routings are faded into the background, as illustrated in FIG. 3 .

There are potentially infinite numbers of service configurations routing to a given service's splitter/resolver from outside that service. Accordingly, there is a potential for very busy visualizations in the UI. With reference to the example shown in FIGS. 2A and 2B and FIG. 3 , the UI can be configured to show only portions of the routings related to that service. For example, users may be mainly interested only in “web” services, and not necessarily other services, in which case the UI can be configured to visualize only web services. As another example, to keep things easy to view in the UI, while there might be more routes in a “kubernetes” router, the system can be configured to only show route(s) most relevant to a user, i.e. based on user input. To see more or other routes, a user can click a “view service” link or similar link to go to another page for rendering in the UI that visualizes the other routes related to that service. Further, the splitter for “web” services has other services, routers and splitters directing traffic to it. While that is possibly too much information to display upon page load, it is necessary to show this traffic when the user clicks or otherwise selects that component.

In some implementations, tools can be used that allow users to zoom in or out, or move the display horizontally or vertically. Such display tools can be similar to those used, for example, in systems such as a learning management system (LMS) like Canvas™, to enable users to use small screens to view large complex visualizations of online courses. FIG. 4 shows a mobile version of a visualization 400, where users can “drag” horizontally to view, and zoom in/out with actions such as “pinching” the screen.

FIG. 5 illustrates that splitters can have a drag-able slider to allow a user to adjust and update the split percentages easily and quickly, all the while the routings 205 are maintained. In some implementations, the ellipses can provide a dropdown menu with more actions. Arrows start from the percentage blocks, making splits more clear and visible. Additional information can be made available on the resolver boxes. A view control 250 can be provided that allows a user to select between a condensed view and an expanded view.

The visualization systems and methods described herein can provide for animation and/or Cascading Style Sheets (CSS) transitions. For example, the arrows can be animated and smoothly “draw themselves” on page load. As updates are made to the configuration files, those changes can appear independently and smoothly, without the visualization 200 having to re-write entirely from scratch just because of one small change.
